OpenRouter amounts are model-list rates, excluding its separately listed platform fees. A missing quote means it was not verified for this comparison; it does not establish that the provider has no such model. Unverified reference figures are not filled with older or inferred prices.

What the image price includes
The table covers the output image component only. Input text, references, text responses, thinking and search can add charges. fal publishes additional search and high-thinking fees for Nano Banana 2. The table is not a guaranteed all-in request price.
Google publishes rounded per-image equivalents while OpenRouter lists image-token rates. OpenRouter estimates use 1,120/1,680/2,520 tokens for Nano Banana 2 at 1K/2K/4K, and 1,120/2,000 for Pro at 1K–2K/4K. Rounding differences do not establish a markup.
Bulk generation and accepted-image cost
If 8,000 of 10,000 paid images are accepted, divide total spend by 8,000 rather than by request count. Add retries, inputs and storage. For a product catalog, begin with a small representative batch and review product fidelity.
A queue of regular generations and Google Batch are different modes. Do not transfer a Batch discount to interactive pricing or another gateway. Google schedules the old Gemini 2.5 Flash Image for shutdown on October 2, 2026; budget new projects around the current family.
